TMS320C6670AXCYP Equivalent & Substitute Parts

Part Overview

The TMS320C6670AXCYP is a fixed/floating-point digital signal processor (DSP) from Texas Instruments' TMS320C66x series, designed for embedded applications requiring high-performance signal processing. This device integrates multiple communication interfaces including Ethernet MAC, PCIe, SPI, UART, and SRIO, making it suitable for complex embedded systems. The part is currently in Last Time Buy status, indicating end-of-life transition. Identifying equivalent and substitute parts is necessary to ensure design continuity and support for legacy systems or to transition to actively supported alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMS320C6670AXCYP is determined by the following critical parameters:

• Manufacturer: Texas Instruments (same manufacturer ensures design compatibility and support continuity)
• Series: TMS320C66x (ensures architectural compatibility and instruction set alignment)
• Type: Fixed/Floating Point DSP (functional equivalence for signal processing applications)
• Package / Case: 841-FCBGA (physical and electrical compatibility with PCB layout)
• Clock Rate: 1 GHz (performance baseline for real-time processing requirements)
• Core Voltage: 1.00V (power supply compatibility)
• RoHS Status: ROHS3 Compliant (regulatory compliance requirement)

The substitute part TMS3TCI6618AXCYP2H is evaluated against these parameters to determine functional and physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TMS3TCI6618AXCYP2H is listed as an MFR recommended substitute. The primary advantage of this substitute is its Active product status, which contrasts with the Last Time Buy status of the TMS320C6670AXCYP. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Selection between the main part and substitute should be based on:

• Inventory Requirements: The main part has 724 units in stock; the substitute has 670 units available.
• Product Lifecycle: The substitute's Active status provides longer-term availability and support compared to the Last Time Buy designation of the main part.
• Compliance Continuity: Both parts meet identical RoHS and REACH requirements, supporting consistent supply chain compliance.

Detailed electrical and mechanical parameter verification is required before final design integration, as complete specification data for the substitute part is not fully provided in this reference.

Frequently Asked Questions (FAQ)

Q: Can the TMS3TCI6618AXCYP2H be used as a direct replacement for the TMS320C6670AXCYP?

A: The TMS3TCI6618AXCYP2H is designated as an MFR recommended substitute and shares the same manufacturer (Texas Instruments) and regulatory compliance status. However, complete technical specifications for the substitute part are not fully documented in this reference. Verification of electrical characteristics, interface compatibility, and package specifications is required before implementation.

Q: Why is the TMS320C6670AXCYP in Last Time Buy status?

A: Last Time Buy status indicates the part is transitioning to end-of-life. Existing inventory remains available, but no new production is planned. This status necessitates identification of substitute parts for new designs or long-term production requirements.

Q: Are both parts compatible with the same PCB layout?

A: Package and case specifications determine PCB compatibility. The main part uses an 841-FCBGA (24x24) package. The substitute part's package specification is not provided in this reference. Physical and electrical compatibility must be confirmed through detailed datasheet comparison before PCB reuse.

Q: What compliance certifications apply to both parts?

A: Both the TMS320C6670AXCYP and TMS3TCI6618AXCYP2H are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in most markets.

Q: How should I select between these parts for a new design?

A: For new designs, the Active product status of the TMS3TCI6618AXCYP2H provides extended availability and support lifecycle. For legacy system maintenance or existing inventory utilization, the TMS320C6670AXCYP remains available. Consult Texas Instruments technical documentation and application notes for detailed compatibility assessment.
